• As for nipples stick to brass. A lot of people go to great lengths to have black nipples - if you can find black brass nipples then go for it, but i'd steer clear of alloy nipples at all costs. Just my tuppence based on personal experiences. If you want to save 10grams by using alloy nipples just got for a shit before you ride your bike, there's better places to save weight IMO.
